4 Claims.

This invention relates to water closets provided for use in railway cars and like locations, or for use under similar conditions, and has for its object generally the provision of a water closet particularly adapted for such use, the parts of which will be so constructed and arranged that up-draft through the closet will be prevented and danger of clogging or jamming of any of the parts of the device eliminated.

The invention relates particularly to a type of water closet heretofore invented by this inventor, and in which a draft member is mounted to swing up to close the closet flushing outlet, while the dump pan is out of sealing relation with the closet bowl during flushing. Linkage and cam mechanism in this earlier structure of this invention has actuated a swinging draft member prior to or as an incident to the initial downward swing of the dump pan in the flushing operation.

This invention has for an object improvement of mechanism of this character wherein the parts may be readily given nice adjustment to cause the desired relative and conjoint movements of the dump pan and draft member and without the need for nice dimensioning and fit in the manufacture.

Another important object of the invention is the provision of a water closet accomplishing its flushing by the dumping of a pump pan and adapted to be sealed against up-draft at all times, the parts of which will be so constructed and arranged that any large object forced past the dump pan will be prevented from damaging the operating mechanism or jamming the parts in service as an incident to its passage by the draft member or resulting obstructions in the path of closing movement of the draft member.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, when taken in connection with the accompanying drawings, illustrates a preferred embodiment thereof.

Referring to the drawings,

Figure 1 is a side elevation of a railway water closet in which the present invention is embodied;

Fig. 2 is an enlarged detailed fragmentary elevation showing certain structural features;

Figs. 3 and 4 are partial views similar to Fig. l and show the parts in different arrangements they assume in the operation of the water closet;

Fig. 5 is a front end elevation, parts being broken away and shown in section; and

Figs. 6 and '7 are fragmentary sectional details of parts of the operating mechanism.

The water closet shown on the drawings, and in which the present invention is embodied, comprises generally a closet bowl 11, a stand 12, a so flush valve mechanism 13, and a flushing mechanism 14. The closet bowl 12 is or may be of ceramic material, having a seat receiving portion 15 and an outlet 16. The bowl 11 fits within and rests upon the stand 12 and the waste is disc5 charged from the stand through a bottom closet outlet 17. The stand is or may be of cast-iron or other suitable material.

A dump pan 18 is provided to close the outlet 16 of the closet bowl, and a draft member 19 is arranged to seal the closet outlet 17 when the dump pan is out of bowl closing position. 'The dump pan 18 is of bowl shape or semi-rounded form, adapted to contain water for sealing the bowl outlet.

A shaft 21 is arranged through bearings 22 of the stand and through a rearward extension 23 of the dump pan. The dump pan is fixed upon this shaft and swinging of the shaft pro duces swinging of the dump pan to and from closing position.

At one end, i. e. the right view of Fig. 5, a counterweight arm 24 is fixed at 25 upon the protruding end of the shaft 21. At the opposite end, namely the left, viewing this figure, the shaft extends loosely through a sleeve 26 which is pro" vided with an outwardly extending arm 27, carrying a pin 28, which is arranged through a slot 29 of a vertically arranged link 31. The link 31 is pivoted at 32 to a hand lever 33, in turn connected or pivoted at 34 to the flush valve mechanism, the lever serving upon manipulation to operate the flush valve to deliver water to the closet bowl at each dumping of the dump pan.

The end of the shaft 21 is formed of square or other non-circular shaft as indicated at 35, and a finger piece 36 is secured upon the end of the shaft 21 against rotation by means of a screw bolt 37. A finger indicated at 38 on the finger piece 36 is arranged in the path of movement of a projection 39 on the arm 27, so that when the lever 33 is lifted the projection 39 is moved toward and then engages the finger 38 to swing the dump pan downwardly in a clockwise direction, viewing Fig. 1, to a dumping position.

This movement of the dump pan is accompanied by a closing movement of the draft member. The draft member 19 is fixed upon a cross shaft 41, arranged through the stand and adjacent the closet outlet 17.

An arm 42 is rigidly fixed upon the shaft outside the stand and this arm is connected by a spring 43 with a second arm 44, the lower end of which is bifurcated and mounted loosely upon the shaft 41, embracing the fixed arm 42, which may be observed in Fig. 6.

The loose arm 44 is provided with a follower roll 47, adapted to engage a cam 48 carried on the end of an arm 49 integral with a clamp collar 51, embracing the sleeve 26 already described.

A set screw 52 is arranged through the clamp sleeve to lock the parts tightly in fixed and adiusted position. The clamp sleeve is provided with a rearwardly extending arm 53, on the end of which is provided a counterweight 54.

The cam 48 is provided with an inwardly extending slot 55, in which the roller 47 rests when the dump pan is in sealing position, and in this position the draft member is swung down and away from the closet outlet 17, being urged to this position by a counterweight arm 50 fixed on the shaft 41.

Beyond the slot 55 the cam is curved arcuately, as indicated at 56, and this portion of the cam swings the roller toward the left, viewing Fig. 1, and holds the draft member in outlet closing position until the flushing action is completed.

By reason of the pick-up connection between the projection 39 and the finger 38, the draft member is swung to a closed position before the dump pan begins to move in its dumping operation, and remains in closed position until after the dump pan has returned to normal position after flushing.

If any obstruction be interposed to the closing movement of the draft member, the spring 43 yields and prevents damage to the parts.

Viewing Fig. 4, which shows the arrangement of the parts during the major time period occupied by the flushing operation, it will be noted that the cam 48 extends somewhat the spring 43 so that the draft member is yieldingly pressed against its seat to accomplish its draft sealing operation.

It will be apparent by reason of the construction of the parts at the shaft 21, adjustment in the timing of the movement of the dump pan and of the sealing member is readily accomplished and accurate formation of the parts is therefore unnecessary.

The counterweight arm 24 returnsthe dump pan to position and the counterweights 50 and 51 return the cam and the other parts of the operating mechanism to their normal positions, as shown in Fig. 1.

If it is desired to flush the entire water closet with hose, both the dump pan and the draft member may be arranged in lowered position by merely lifting the counterweight arm 24.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
